"I'm running the New York Marathon this year and raising funds for the J/P Haitian Relief Organization," the former "Baywatch" star, 46, tweeted Sunday.

Anderson's goal is to raise $500,000 and she has raised $8,000 so far, according to her fundraising page. It's going to take her an awfully long time to run 26.2 miles in slow motion ...

Meet Cordell Broadus, aka Snoop Dogg's son (or Snoop Lion now, I think? I'm still not really sure). Cordell is still a high school junior, but he's also one of the most promising wide receivers in the country. And he already has the mouth of a sports superstar, it seems, as he recently chimed in on the Sunday departure of coach Lane Kiffin of the University of Southern California, one of his more attractive options.

"I feel that he should have been fired a while ago, and USC is going to raise the bar now because the new coaching staff next year and I'm anxious to see what they are going to look like," Cordell told 247Sports.

This is like rain on your wedding day. Pop star and noted attachment mom Alanis Morissette and her husband are now being sued by their former nanny, Bianca Cambeiro, over allegations she wasn't paid overtime or provided with rest breaks, according to court documents posted on Radar Online.

Cambeiro worked for Morissette in 2011 to care for her son, Ever. In the suit, Cambeiro claims that while working three to four days a week, at $25 per hour, she wasn't allowed to leave the room while Ever was sleeping, unless a parent was present.

After a final 8 episode-run that unfolded at a break-neck pace, multi-Emmy award-winning series "Breaking Bad" is dead, and at last, at peace.

ABC News

The Amanda Knox trial begins, again, in Italy today. Knox's second appeals trial in her British roommate's slaying opened in Florence, but the 29-year-old former exchange student, who was freed in 2011 after spending years in jail, was nowhere to be found in court. In this trial, the third in the case, the court is re-examining forensic evidence to determine whether Knox and her boyfriend played a role in the death of Meredith Kercher.

The Court of Cassation said the acquittal was full of "deficiencies, contradictions and illogical" conclusions.
